BURNER FOR COIVIPOUND BLOWPIPES OR BRAZERS.

SPECIFICATION forming part of Letters Patent No. 586,066, dated July 6,1897.

Application filed March 22, 1897. Serial No. 628,760. (No model.)

To all whom it may concern:

Be it known that I, VALTER SAMS, of the city of IVarrensburg, Johnsoncounty, State of Missouri, have invented certain new and usefulImprovements in Burners for Compound Blowpipes lor Brazers, ot' whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part hereof.

My invention relates to burners for compound blowpipes and brazers andit consists of the novel construction, combination, and arrangement ofparts hereinafter shown, described, and claimed.

Figure l is a plan View of my improved burner as seen looking in thedirection indicated by the arrow lin Fig. 2. Fig. 2 is a sectional viewtaken approximately on the line 2 2 of Fig. l. Fig. 3 is a modification.

The pipe 3 carries the gas, hydrogen, or hydrocarbon to the burner, andthe pipe fl carries the air or oxygen to the burner, the tip of the pipe4 being inside of the tip of the pipe 3.

The burner consists of the bell-shaped portion 5, the neck 6, attachedto or formed integral with the bell-shaped portion 5, and the foraminousbody 7, stretched-across the opening in the neck 6 and held in positionby the ferrule 8, which ferrule also engages the tip of the pipe 3 andholds the burnerin position relative to said pipe. A series ofperforations 9 are formed in thebell-shaped portion 5 and extend in aline around said portion 5 at a point near its junction with the neck G.The bell-shaped portion 5 forms the iiaring discharge opening or nozzlefor the blowpipe or brazer. The neck 6 is substantially the samediameter as the tip of the pipe 3.

The foraminous body 7 may be formed of Iine Wire-gauze, or of anysuitable material, and said body is placed in position across the innerend of the neck G, with its edge extending outside of said neck and bentforwardly, and the ferrule 8 is inserted upon the neck 6, thus bringingthe edge of the foraminous `body 7 inside of the ferrule and outside ofthe neck and holding said edge securely in position. The neck G is thusiix'ed in position in one end of the ferrule 8, and the tip of the pipe3 is inserted tightly in the opposite end size and shape of the flameand secure perfeet combustion of the gases and prevent the ilame frombecoming extinguished under a high pressure of gas and to prevent theflame from communicating with and exploding the gases where explosivemixtures are used.

The object of the foraminous body 7 is toI form a screen through whichthe gas, hydrogen, orhydrocarbon must pass, and said foraminous body maybe concave, convex, or iiat, as desired.

In the modication shown in Fig. 3 the foraminous body 7 is placed inposition against the outer edge of the bell-shaped portion 5, and theedge of said foraminous body is turned backwardly and inwardly, forminga connection with said bell-shaped body and said foraminous body 7, andsaid foraminous body 7 is concaved. The tube ll is formed integral withthe bell-shaped body 5 and projects backwardly, and the rear end of saidtube is slotted to form spring-arms l2, the expansive tension of whichwill hold the burner in position when the tube ll is inserted in the endof the pipe 3.

I claiml. In aburner for compound blowpipes and the like, a bell-shapedbody forming a discharge-opening for the gas-pipe, and a foraminous bodysecured in position between the tip of the blowpipe and the innersurface of said bell-shaped body in such a way that the gas must passthrough said foranlinous body, said foraminous body having an opening inits center to allow the air from said air-pipe to y pass freely throughsaid foraminous body, substantially as specified.
